The system uses a chirp baseband signal which 10-60MHz up-chirp signal and 60-10MHz down-chirp signal which is generated using Direct Digital Synthesizer (DDS) of AD9850 with 125MHz clock rate. The baseband signal is up-converted at X-band using a mixer with 9.035GHz Voltage Controlled Oscillator (VCO) to be transmitted at frequency of 9GHz. The system uses a bandpass filter (BPF) made of lumped elements to eliminate spurious signals produced by the DDS at the transmitter, and a lowpass filer (LPF) at the receiver. The system also uses a microstrip BPF of Square Loop Resonator (SLR) type as RF filter for X-band frequency. The results show that the system has 10-60MHz bandwidth for baseband signal with 10MHz cut-off frequency for LPF, while RF filter has the bandwidth response of 49MHz at the center frequency of 9.0015GHz.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Band-pass filter (BPF),Direct digital synthesizer,Frequency-modulated continuous waves,Simulation systems,Spurious signals,System simulations,X-band frequencies,X-band weather radar[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Direct Digital Synthesizer (DDS),frequency-modulated continuous-wave (FMCW),system simulation,X-band weather radar[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICWT.2017.8284154[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
